Design Features

Alumina ceramic terminals (also known as ceramic rails) are key components designed for high-performance electrical equipment and are 

widely used due to their excellent electrical insulation, high temperature resistance and mechanical strength.

Precision-machined Holes and Rails Design

The terminal block design incorporates multiple precision-machined holes and rails, providing stable and precise connections and secure 

mounting.

High Hardness and High Strength

The high hardness (Vickers hardness 15.7 GPa) and high strength (flexural strength 330 MPa) of alumina ceramic ensure structural stability 

under high pressure and high temperature conditions.

Superior Electrical Insulation Properties

Excellent electrical insulation properties ensure safe operation under high voltage environments, preventing electrical faults.

High Temperature Resistance

Excellent high temperature resistance (maximum operating temperature up to 1650℃) allows the terminal blocks to maintain performance

 even under extreme temperatures.

Application areas

Electrical Equipment

Widely used in high-voltage and high-temperature electrical equipment, such as transformers, motors, and switchgear.

Industrial Applications

Used in industrial machinery and systems requiring high precision and reliability, including control systems and sensor interfaces.

High-Temperature Environments

Suitable for high-temperature industrial applications, such as heat treatment equipment and furnace temperature control systems.

Specialty Equipment

Also used in chemical processing equipment and laboratory instruments due to its corrosion resistance and mechanical stability.

Alumina ceramic terminal blocks offer high reliability and safety for modern electrical and industrial equipment through their superior 

performance and custom design. Their durability and precise connection capabilities make them crucial in demanding technical applications, particularly in high-temperature or high-voltage environments.
